Yes a hurricanes need water to continue to move as there becomes less water the weaker it will be

B.  It’s not fed with moisture on land.

100% ;-)

Explanation: Wind speeds up to 150 mph. Once a tropical system moves inland, the storm will usually weaken rapidly. This is due to the lack of moisture inland and the lower heat sources over land. ... While the sustained winds are reduced because of the dampening effect of larger roughness over land.

Humid continental climate is found in the interior of continents between the 30 and 60 degrees latitude, but usually above the 40 degree line.   40 degrees north of the equator means less direct sunlight and therefore less warmth.   this climate is mainly found in the northern hemisphere since there are no major landmasses in the southern hemisphere.  if you live in northern indiana, you know all about humid continental because that is the climate type you have!
